1587: The Pacification of Kyūshū and the Edict Expelling Christian Missionaries
Hideyoshi sent an army of over 200,000 into Kyūshū, forcing Shimazu Yoshihisa's surrender and pacifying nearly the entire island. On his return journey through Hakata, he issued an edict expelling Christian missionaries, prompted in part by concerns over the destruction of shrines and temples and the trafficking of Japanese people by Christian daimyo and their associates.
